Answer:
Air pressure goes on decreasing as we go higher up, so at high altitudes, the atmospheric pressure becomes less than the pressure exerted by the blood inside the body. This causes some of the blood vessels burst and the nose starts bleeding.

They are all living organisms
Explanation:
A cactus, a house fly, and the grandmother all are living organisms. All the things show characteristics such as growth, metabolism, reproduction, etc. Thus, all can be considered as living things.
What are living organisms?A living organism is composed of different types of cells. The cell is the basic unit of life. These cells divide, and the body of the organisms show growth due to the increase in the number of these cells.
A cactus, a house fly, and the grandmother all are living organisms and show the defining properties of living things. These properties include growth, metabolism, and reproduction.
All the organisms grow with time as the cells undergo division and show metabolism as the cells undergo different reactions such as respiration, etc. All these organisms reproduce to form new organisms which are similar to themselves through the process of sexual and asexual modes of reproduction.

Answer: the grass would be burnt
Explanation:
Fire
The resulting event when a fire moves through a grassland ecosystem are Destruction of Vegetation, Loss of Habitat, Nutrient Release, Changes in Species Composition and Regeneration and Succession.
A biological system is a geographic region where plants, creatures, and different living beings, as well as climate and scene, cooperate to frame an air pocket of life. Environments contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
The four environment types are characterizations known as counterfeit, earthly, lentic and lotic. Environments are portions of biomes, which are climatic frameworks of life and creatures. In the biome's biological systems, there are living and nonliving natural variables known as biotic and abiotic.

in their crops and herds?
A. The breeders choose organisms with the most
desirable traits and breed them.
B. The environment selects the traits that are
passed on, and the breeders have no control over
it.
C. Artificial selection is a theory and does not

A animals and plants have sources
I think
Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits.Thus, option A is correct.
What plant and animal breeders process artificial selection?Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits. Humans have carefully selected a wide range of plants and animals for thousands of years, including agricultural species with higher yields.
Instead of allowing the species evolve spontaneously without human involvement, as in natural selection, people chose animals or agricultural products based on desirable qualities, a practice known as "selective breeding,” or artificial selection.
Therefore, The breeders choose organisms with the most desirable traits and breed them.

Describe genetic linkage

Describe how chromosome maps are created
Calculate the distances between three genes on a chromosome using a three-point test cross
Long before chromosomes were visualized under a microscope, the father of modern genetics, Gregor Mendel, began studying heredity in 1843. With the improvement of microscopic techniques during the late 1800s, cell biologists could stain and visualize subcellular structures with dyes and observe their actions during cell division and meiosis. With each mitotic division, chromosomes replicated, condensed from an amorphous (no constant shape) nuclear mass into distinct X-shaped bodies (pairs of identical sister chromatids), and migrated to separate cellular poles.

Does tap water need to resist shifts in pH? Why
or why not?
The conversion of carbonic acid to CO2 raises the pH level. People rarely need to adjust the alkalinity of their drinking water. Because alkalinity acts as a buffer to reduce pH swings, tap water should have a low alkalinity level.
Why is water's pH significant?Most chemical and biological processes in water are influenced by pH. It is a major environmental factor limiting species distributions in aquatic habitats. Different species thrive in different pH ranges, with most aquatic organisms flourishing between pH 6.5-8. The pH of water used for drinking or cooking is critical. Water that is too alkaline or too acidic is generally unhealthy to drink and can damage appliances and pipelines. Water pH levels are typically between 6.5 and 8.5, which is considered normal. The pH of a solution is a measure of its acidity or alkalinity, as well as its concentration of hydrogen ions. Normally, the pH scale ranges from 0 to 14.

While looking at a slide you observe an unknown crystal lying next to a red blood cell. The crystal is about 2.5 times the diameter of the red blood cell. What is the size of the crystal in um?
The size of the crystal lying next to the red blood cell is roughly 17.5 um (micrometers).
Red blood cells are the most numerous cells in the human body. They are often known as RBCs or are commonly called erythrocytes. They get their name from their bright red color, which they in turn get from a protein they contain called hemoglobin. This protein is responsible for carrying oxygen from the lungs to the various tissues of the body. Erythrocytes have a diameter that ranges from 6 to 8 micrometers.
In the question, it states that we observe an unknown crystal lying next to a red blood cell. Being unknown, we cannot directly know its size. However, the question offers context as to the size of the crystal by stating that it is 2.5 times the diameter of the red blood cell. Through this information, and with the diameter of the red blood cell ranging from 6 to 8 (7 on average), we can infer that the size of the crystal is roughly 17.5um.

Which statement is the best example of how society affects the use of technology?
A. Some people who are concerned about climate change get their power from solar or wind energy.
B. Irrigation systems are used to deliver water to crops that grow in fields,
C. Solar panels can generate power in parts of the world where there is plenty of sun throughout the year.
D. Regions that are sunny most of the year have more farms than cold regions.
The statement which is the best example of how society affects the use of technology is: A. Some people who are concerned about climate change get their power from solar or wind energy.
Technology can be defined as a branch of knowledge which typically involves the process of applying, creating and managing practical or scientific knowledge to solve problems and improve human life.
Basically, technologies are applied to many fields in the world such as;
Medicine.Information technology.Cybersecurity.Engineering.Environmental.Generally, like all human creation, technology has its demerits or negative externality and as such it limits the manner in which it is adopted and use in different societies around the world.
For instance, the use of hydrocarbons such as fuel for the generation of power, causes an emission of carbon gases which increases the chance of global warming and by extension a climate change. Thus, some people who are concerned about this negative impact are likely to get their power from solar or wind energy.
In conclusion, the best example of how society affects the use of technology is that some people who are concerned about climate change get their power from solar or wind energy because they do not pollute the environment.
